For the hydrogen internal combustion engine with port fuel injection, H2 into intake port from injection system will expand, which will block the entry of air. Two types of injection modes, the dual injection with symmetric arrangement and that with spaced arrangement along the axis of intake port, were proposed to improve the blockage of intake port. And the effects of three types of injection modes...
An experimental study on the effects of compression ratio (i.e. 10:1, 12:1) on the combustion and emission of a hydrogen enriched natural gas engine under different excess air ratio is reported. The experimental data are compiled on a turbocharged spark-ignition engine using 55% (volumetric ratio) HCNG (hydrogen enriched natural gas) fuel under MAP (manifold absolute pressure) of 50 kPa, spark-timing...
